For a better understanding of the present invention, embodiments thereof will be described below with reference to the accompanying drawings.

As shown in fig. 1, an automatic water adding structure mainly comprises a tee structure 1 and a sleeve 3 connected with the tee structure 1, wherein a first end 11 of the tee structure 1 is used for connecting a water inlet of a vacuum tank 2, the first end 11 and the water inlet connecting structure of the vacuum tank 2 can be in flange connection, a second end 12 of the tee structure 1 is used for exhausting, in addition, a third end 13 of the tee structure 1 is provided with the sleeve 3 extending into the end and extending beyond a port of the first end 11, and the joint of the third end 13 and the sleeve 3 can be sealed by glue or threaded connection. For example, an outer wire is disposed outside the sleeve 3, and an inner wire that is engaged with the outer wire is disposed at the third end 13, so that a sealing structure is formed by engagement of the inner wire and the outer wire. It is also desirable to make the outer diameter of the sleeve 3 smaller than the inner diameter of the first end 11 of the tee structure so that a gap for venting air is formed between the inner diameter of the first end 11 and the outer wall of the sleeve 3. Here, the sleeve 3 is a sleeve made of soft material, such as a flexible hose made of PVC, so that the sleeve 3 easily extends from the first end 11 of the tee structure 1 and beyond the port of the first end 11 after extending into the tee structure 1 from the third end 13.

It will be appreciated that in the above described embodiment, when the inner diameter of the third end 13 is larger than the outer diameter of the casing 3, it is possible to connect with the casing 3 and achieve a seal with the outer wall of the casing 3 by providing a reducing formation at the third end 13.

It should be noted that the port of the second end 12 of the three-way structure 1 herein may be arranged to face upward. Of course, the exhaust port is not limited to be upward, and the exhaust port may also be downward, for example, the second end 12 is a U-shaped structure, and both ends of the U-shaped structure are opened downward, wherein one end of the U-shaped structure is used as a part of the second end 12 of the three-way structure 1 and keeps it in a vertical state, so that a section of the second end 12 is in a vertical structure rather than a full horizontal structure, in order to prevent water from overflowing therefrom during the exhaust process, and at the same time, the other end of the U-shaped structure is downward to exhaust. In addition, the orientation of all the structures of the second end 12 including the ports is not limited, and it is needless to say that all the second end 12 may be in a horizontal state. It will be appreciated that the second end 12 can be constructed so long as water is filled into the vacuum tank 2 and air in the vacuum tank 2 is completely exhausted, and then water can overflow through the port of the second end 12.

In the above embodiment, the sleeve 3 located outside the third end 13 is provided with the first switch valve 4, the second end is provided with the second switch valve 5, and since the electric ball valve is generally used for cutting off or connecting a medium in a pipeline, and can also be used for adjusting and controlling a fluid, which is a common switch valve for industrial automation process control, the first switch valve 4 and the second switch valve 5 both use the electric ball valve, wherein the first switch valve 4 is used for timely closing the port of the second end after the vacuum tank 2 is filled with water to prevent water from overflowing from the port of the second end, and the second switch valve 5 is used for timely closing the sleeve 3 sleeved on the third end 13 after the vacuum tank 2 is filled with water to prevent water from being continuously injected into the vacuum tank 2.

In order to detect whether the vacuum tank is full of water, a non-contact level gauge 6 is also provided at the second end 12. The non-contact liquid level meter 6 and the second switch valve 5 are sequentially arranged along the exhaust direction, namely the non-contact liquid level meter 6 is arranged at the front end of the second switch valve 5 along the exhaust direction, and when the non-contact liquid level meter 6 detects that water is filled, the second switch valve 5 is closed, so that the water is prevented from overflowing along the port of the second end 12.

In the above embodiments, the non-contact level gauge 6 is an ultrasonic level gauge. During measurement, ultrasonic pulses are sent out by a sensor of the ultrasonic liquid level meter, sound waves are received by the same sensor after being reflected by the surface of the liquid and are converted into electric signals for feedback, and then whether the water level reaches the set height or not is detected, namely whether the water is filled.

The non-contact level gauge 6 may also be of another construction, for example it comprises two rings 61 arranged one above the other in the second end 12. Specifically, the second end may be connected to the elongated portion, two rings may be provided up and down inside the elongated portion, the metal ball 62 may be provided between the two rings, and a detection switch 63 for detecting the position of the metal ball 62 may be further provided at the upper ring. Thus, when the vacuum tank 2 is filled with water, the metal ball 62 floats upwards along with the water, and when the detection switch 63 detects that the metal ball 62 is close to the upper ring 61, the metal ball indicates that the water is filled, and the second switch valve 5 is closed in time.

The working process of the utility model matched with the two-phase flow pump is as follows: when the two-phase flow pump is used for pumping water, the two-phase flow pump is firstly connected with a water outlet of the vacuum tank 2, the first end 11 of the automatic water adding structure is connected with a water inlet of the vacuum tank 2, and the non-contact liquid level meter 6, the first switch valve 4 and the second switch valve 5 are respectively connected with the controller. In operation, the non-contact level gauge 6 first detects whether there is sufficient water in the vacuum tank 2, and if the non-contact level gauge 6 does not detect water, it indicates that the vacuum tank 2 is not filled with water. At this time, a detection signal of the non-contact liquid level meter 6 is fed back to the controller, the controller controls the first switch valve 4 and the second switch valve 5 to be opened, water enters the vacuum tank 2 through the sleeve 3, air in the vacuum tank 2 flows through a gap formed by the outer wall of the sleeve 3 and the inner wall of the first end 11 of the three-way structure 1, and is finally discharged through the port of the second end 12 until the non-contact liquid level meter 6 at the port of the second end 12 detects the water, which indicates that the vacuum tank 2 is filled with the water. At the moment, a detection signal of the non-contact liquid level meter 6 is fed back to the controller, the controller controls the first switch valve 4 and the second switch valve 5 to be closed, and the two-phase flow pump starts to work to pump water; when the water pumping process of the two-phase flow pump is finished, the water in the vacuum tank 2 is in an unfilled state, and before the two-phase flow pump is needed again, the non-contact liquid level meter 6 can detect whether the vacuum tank 2 contains enough water again, and the processes are repeated in sequence.

It should be noted that while various embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous modifications, changes, and substitutions will occur to those skilled in the art without departing from the spirit and scope of the present invention. It should be understood that various alternatives to the embodiments of the utility model described herein may be employed in practicing the utility model. It is intended that the following claims define the scope of the utility model and that the module compositions, equivalents, or alternatives falling within the scope of these claims be covered thereby. Those skilled in the art will appreciate that the embodiments described above are illustrative of some, but not all embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
